nmmn smms PATENT OFFICE AN'ICJNY WERTETNTBRUCH, OF DETROIT, MICHIEGAN,ASSIGNOR TO LARB;GLWE MILL- ING CO1VJIPANY, OB DETROIT, MIGHIGAN, ACORPORATION Q1 OBIO The invention relates, to bag filling mm chines analmore partic1ll2fily to av means for increasing the c0ntent by weight 0l'tl1e fillecl bag. T0 tl1is encl the invention cousists in the peculiarconsbrudi0n 0f mea ns f0r compacting ehe material wlthin the bag cluringfil ling operations as hereinafter Sei; forth.

In tl1e dmwings;

Figure 1 is' a sicle elevation 0f the manchine.

Figure 2 is 21 plan view thereof.

Figure 3 is a cross section.

In the filling of bags with granular material it is nsual t0 place themouth of tl1e bag amund the filling spout and t0 support the botton1 011a shelf 0r platform. l/Vl1ex'e the n1ate-rial is dischargecl from thespout by gravity it would be loosely arrangecl und therefore greater inbulk than When in a compacted stae. Consequently it is cliflicult toplace within the bag tl1e I"ull quantity by weight which it is designedt0 hold. T0 :w0icl this difllculty I l1ave devised 1ny mechanlsm f01irnparting an oscillatory m0vement t0 the bag supporting platlor1n suchms T0 efi"ect rl1e comym.cting 0'E the 1naterial by inertiaanal withoutclisplacernent 0f tl1e bag in relation t0 its support.

In detail A represents ehe Clischzuge spout fron1 a ba.g fillingmacl1ine 0E any sultable construction ancl B the bag co be fillecl l1V-ing its mouth surronncling saicl spout. C is a sl1elf 01' platform forsupp-orting the b-ottom 0f ehe bag and D a vertically extencling Wallrising fro1n saicl shel:f against which ehe bagdniay rest.

The platfonn C und Wall D are mountecl upon an osclllatory fmmecomprising the lwriz-ontally extending parallel bars E shown asmetallicangle ba1s. F is a link pivotally attachecl to the rear encl 0'ftl1e bzus E by a holt 01 pivot pin G. H are stationary bea1ns 011opposite sides 0'f the bars E und whlch support the link F tln=ougl1tl1e mecli.um 0f a holt I. J is a man]: shalt extencling transverselyacross tl1e ba1s E and the be2uns H being ournale:d in bearings K uponsaicl bemns und having its cranks 01 eccentric portions engagingbearings L 011 the l02us E. M is a pulley mountetl on the shaft J 21ncld1iwan by a belt 01' otl1er suitable drive connection 110t sl1own.

With t-he construction as clescribecl, lt Will be noted that theplatf'orm C anal WLll D a1e su'pportecl 011 thelorwarclly projectingportion of ehe bars E, whi;ch in tu1 n are supported by the. crankJ 2mdlink- F. Tl1us, When the pulley M is driven in tl1e cli1ectioninclicated by the arrow, an; -oscillatory movement Will b.e impartgclto. the bars E zu1d platform C ancl Wall D ca rried there by. The. clirection 0f movemeni; is such that when the platform Changes fronn a,-downward to an upward moVement lt is als-o travelling outwarcl buab-clecre asing velooity. Thus, inertia Will cause tl1-e compacting 0ftl1e material against both the bottom and the rear Wall ancl Will holdtl1e bag from relative clisplaeement. On the 0tl1er hancl, 011 the rexersal from upwarcl to clownwarcl movement, gravity Will assist inovercoming the inertia 01' the clisplacelnent of the bag thereby. Thetotal effect is to compact the conbent of the bag during tl1e fillingoperation so filmt the full quantity may 109 plaoecl berein.

vVlmt I claim as my invention is:

l. The comloination with means for dis* cluu'glng material int0 themouth 0'E a bag, oi' n suppo1t f01' tl1e botton1 und 0ne Sicle 0f thelmg aml means f01' in1parting t0 saicl supportan oscillatmy movement in-a vertical plane und in a direction t0 press the sicle support againstsaid bag onreversal f101n down- Ward to upvvard movement of t he bottomsupport therefor.

2. The combination with means for discharging material into tl1e moutl10f a bang, of a support f0r saicl bag comprising a horizontallyextencling bar, a pivotal link for supporting one end 01 saicl bar, arevoluble crank for engagin'g an intermecliate portion 0'f said bar anda platform and side Wall for engaging ehe bag mountecl 0n the free endof said bar.

3. The combination with means for diseharging material into the mouth ofa bag, of a support for saicl bag comprising a pair o1. parallelhorizontally extending bars, a swinging link :for pivotally connectingancl supporting the rear encls 0l' said bars, a revoluble crank shaftfor erigaging the intermediate portion 013 said bars ancl a platforrnancl side supporting Wall f0r the bng mountecl 0n tl1e .l'oxward enclportion 0f saicl ba1s.

4. The combination with 1neans -for discharging material into tl1e m0uthof a bag,

of a support for saicl bag comprising a horizontally extencling bar, apivotal link for supporting the rear end of saicl bar, a crank shai'tf01 engaging an intermediate portion of saicl bar 110 oscillate tl1esame in a vertical plane ancl in a direction t0 reverse from downward t0upward movement While saicl bar is also moving outwardly, and a platformand rear supporting Wall f01' saicl bag mountecl on said bar.

5. The combinat-ion with 1neans f01 d1scharging material into the mouth0'f a bag,

of a support for saicl bag comprising a platf0rm anal a verticallyextending W2Lll mountecl on saicl platform against which the bag isadaptecl t0 rest, ancl means for imparting an oscillatory movernent t0saicl support in a direction to retain the bag from relativeclisplacement by inertia.

6. The combination with means for discharging material into the mouth 01a c0ntainer, 0f a support for the bottom and one sicle of the containercomprising a platform and a vertically extencling Wall mounted on saiclplati'orm, saiol platform adapted to be mountecl on a frame comprising apaix of horizontally extending parallel bars, and means for imparting anoscillatory movement to said :frame in a vertical plane and in adirection to press the Wall against said containe1 0n reversal fromdownward to upward movernent 0f the platform.

7. The combination With means fo1 discharging material into the mouth ofa bag, 0l" a support f01' said bag comprising a horiZontally extendingbar, means associaterl with said bar 7Eor imparting an oscillatorymovement to said bag, ancl a platform und sicle Wall f0r engaging thebag mounced 0n said bar.

In testimony whereof I affix my signature.
